swabs for detection and susceptibility of Trichomonas
Demonstration of Trichomonas
vaginalis trophozoites is usually done by preparing wet mounts
made from vaginal swabs or scrapings. If the specimen cannot be
examined immediately, it should be preserved in PVA and stained smears
T. vaginalis is usually highly susceptible to metronidazole.
However, cases of resistant T. vaginalis have been reported and
may be increasing. There are no standardized guidelines for the
identification and treatment of these organisms. In 1978, an in
vitro drug susceptibility test was developed by J.G. Meingassner.
It can be used to determine the extent of resistance of a trichomonad
isolate to the 5 nitroimidazoles. This test is performed at the
Division of Parasitic Diseases on isolates that are received from across
the country. Test results are forwarded to the CDC/NCHSTP/DSTDP
and are then communicated to the submitting physician.
